L-'Be it known thatLlIsAAc Trclnof the city, countyand State of New York, have invented a new and useful Improvement in Windmills, of which the following is a full, clear, and exact description, referencebeing'had to the accompanying drawings forming-part of this specification, and in which-.-

My invention consists iny a combination of independent wind-boards opposed to the direct 'action of the wind, and arranged to. reciprocateV intermediately'or alternately relatively to eacli other, under the .control of valves or shutters, which adt'n-t or shut -oif the wind-from saidboards in succession, in'such a' manner as Vthat by i* .a suitable connecti'on'of said boards with a many-cranked shaft or other mechanical expedient, and appropriate attachment of the valves or shutters, a continuous motion is kept up by the'successive action-orf the wind-boards, which may either be used direct, as a vdriving-power, or through the instrumentality ofa wegh'tfraised by said force and clock-work or gear under its control, or the equivalents of such applicancesmay serve to store 'power for future use. Y f I f Referring to the accompanying drawing, A, B, and() represent wind-boards, of' which theremay be any suitable number hinged, it may be, in the same line orplane, as at a b c, so as to be capable ofa swinging backward and forward motion relatively to windows or openings D, one to each wind-board, and'previded with' shutters or valves al, hu`ng on central axes, in crderltliat they'may open and close in a. similar manner-.to the slats4 of a Venetian blind or shutter. E E E are pitmen, connecting the wind-boards A B C with cranks EF F, of a general shaft, G, that are pitched or set at'intermediate throws, so that by the successive back. action of the several Vwind-boardaat regularbut intermediate intervals relatively to each other, by opening the shutters, d, -of their respective windows, to expose theni't'o theforce of the wind, they serve to rotate and keep up aV continuous motion to the shaft G, the shutters d of the several windows being successively or intermediately closed in the return stroke of the wind-boards, toprevent a counteracting linfluence of the wind, by eccentrics H H H, through rods f and levers g, acting on bars 7L, connected with the shattered of thel several windows respectively,` and said eccentrics afterwards serving to open the shutters, to re-epose, successively' or intermediately, the boards A B'C to thewind, which, in producing abackward rocking action of them, keeps up a continuous motion of the -shaft G. This action of the Wind, itvwill be perceived, is a direct one `upon the faces ofthe boards; thus the utmost available force is obtained, and wind-slip avoided, Of course the whole apparatus may be hung or suspenlded, as in the case of acomin'cn windmill, to adjust itself to the changing direction of the wind. The shaft Gr` may either be used direct for various drivingpu'rpos'e's, or asl a means for communi-` eating power, .by .belt and pulleys' or other gear,`to'a secondary shaft.' y

. To obviatethe'irregularity which attaches to wind asia Vmotive-power,.it has frequently been proposed to employ the prime-morenas an agent for storing power, by causing it to raise a weight or weights that intheir descent operate `through suitable mechanism to work a driving-shaft. The utility. of snch"` an arra'ngementin calms or light winds will be readily understood. Such an arrangement or combination with the windtnotor' herein previously described, is represented'in the drawing, where I is an endless rope or chain, wound round'a drum, J, on the shaft` Gr, and over or round sheaves or pulleys K L, to, from, and round a barrel, Mt' This rope has suspended on it, in one of its lines of run, a weight, N, thatLas the shaft Gis rotated by the action of the Wind-boards, is raised from any suitable depth, by the'straig'htening'of such line'of run from a slingslike position, throughthe action on the rope of the drum` J, saidfweight afterwards serving,.on its descent, to, through V.the rope or chain, communicate motion to the barrel M, and from it, by suitable gear or mechanism, yto a driving: shaft, O. A second-weight, P, may be applied to the rope or chain to keep the slack steady, and prevent its entanglement with other parte; t Y V i Operating in connection with such or other like powers, as, for instance, with the `train of wheels of which 'the-storing-powcr is composed, is a pneumatic `or iiuidfdrag, to pioduceunifolmity of speed aathe actionnof the motor dr driving-shaft, that without a controlling device would be subject, from the-character and action of the driving force, to great irregularity in velocity. This pneuniete o-r -nid drag is represented as consisting of'aj cylinder, @having a small orifice, m, at or` neer its one or -closed end, or itmay be, where beth-l ends are closed, provided with orifices at or nea-r opposite ends, said cylinder being tted with a -piston that is.

reciprocated by e rod, through a crank, r, driven by the train, of gearing es before referred to, so that on there being any tendency to acceleration in speed ofthe driving-shaft, the piston attached to the rod n will be proportionately quickened and znade to encounter increased resistance by a more forcible expulsion ef the air within the cylinder Q, through the orifice m, or greater compression of the air Within said cylinder than `there is free escape for, thus causing the piston to act as n, drag, which, as the speed slaekcns again, relieves itself by thev slower action of the piston, and consequently readier escupe for the air thmugh the orifice in the end of the cylinder. 1"*

What is .here claimed, and desired to be secured by`Lette1-s Patent, is-' The combination, with the many-cranked driving-shaft G, or-other suitable driving-mech'nnismyof the recipf roceting wind-boards A B C, dierently pitched or set for successivefction in likedirections, intermedietel'y to eachother, and controlledlby Valves or shutters (l, subsi-:antially as specified.i
